Optimización del proceso de pasteurización de la leche utilizando un controlador lógico programable PLC y monitoreo con un interfaz humano máquina HMI, con fines de desarrollo tecnológico y didáctico en la planta de lácteos de la estación experimental TUNSHI – ESPOCH.

Abstract

It has made de optimization of a milk pasteurization by a PLC with HMI connection with technology and development purposes, it was executed in Tunshi-ESPOCH Experimental station. This optimization was achieved through the automation. Prior to the development of this work, an investigation of the system was held at to dairy plant in order to detect possible faults in the pasteurization process. After studying and understanding the operation of equipment within the plant, the process was materialized in a flow chart for further processing in GRAFCET first and second level, concluding in PLC programming. Installation and wiring with the process control system. It was made according to local regulations. The optimization was applied in changing times on and of diverter valve. Prior to an experimental study, the valve allows heating system. Programming was schematized in TIA Portal V13 Professional Software, also it is loaded in the PLC S7-1200 and a touch screen KTP 400 Basic Color, software, wich has its respective license. The contribution of the career in this project it materializes in automation that contributes to the optimization of an industrial process, analyzing as a maintenance to improve by a technology transfer. In addition, generation of user manuals, maintenance and security to ensure the operation, management and equipment life.
